Technology
The Intel
®
5 Volt FlashFile™ memory renders a variety of density offerings in the same package. The 4-, 8-,
and 16-Mbit FlashFile memories provide high-density, low-cost, nonvolatile, read/write storage solutions for a
wide range of applications. Their symmetrically-blocked architecture, flexible voltage, and extended cycling
provide highly flexible components suitable for resident flash arrays, SIMMs, and memory cards. Enhanced
suspend capabilities provide an ideal solution for code or data storage applications. For secure code storage
applications, such as networking, where code is either directly executed out of flash or downloaded to DRAM,
the 4-, 8-, and 16-Mbit FlashFile memories offer three levels of protection: absolute protection with V
PP
at
GND, selective hardware block locking, or flexible software block locking. These alternatives give designers
ultimate control of their code security needs.
This family of products is manufactured on Intel
®
0.4
µm
ETOX™ V process technology. They come in
industry-standard packages: the 40-lead TSOP, ideal for board-constrained applications, and the rugged
44-lead PSOP. Based on the 28F008SA architecture, the 5 Volt FlashFile memory family enables quick and
easy upgrades for designs that demand state-of-the-art technology.

INTRODUCTION

Product Overview
This datasheet contains 4-, 8-, and 16-Mbit 5 Volt
FlashFile memory specifications. Section 1.0
provides a flash memory overview. Sections 2.0,
through 5.0 describe the memory organization and
functionality. Section 6.0 covers electrical
specifications for commercial and extended
temperature product offerings. Section 7.0 contains
ordering information. Finally, the 5 Volt FlashFile
memory family documentation also includes
application notes and design tools which are
referenced in Section 8.0.
The 5 Volt FlashFile memory family provides
density upgrades with pinout compatibility for the 4-
, 8-, and 16-Mbit densities. The 28F004S5,
28F008S5, and 28F016S5 are high-performance
memories arranged as 512 Kbyte, 1 Mbyte, and
2 Mbyte of 8 bits. This data is grouped in eight,
sixteen, and thirty-two 64-Kbyte blocks which are
individually erasable, lockable, and unlockable in-
system. Figure 4 illustrates the memory
organization.
SmartVoltage technology enables fast factory
programming and low power designs. Specifically
designed for 5 V systems, 5 Volt FlashFile
components support read operations at 5 V V
CC
and block erase and program operations at 5 V and
12 V V
PP
. The 12 V V
PP
option renders the fastest
program performance which will increase your
factory throughput. With the 5 V V
PP
option, V
CC
and V
PP
can be tied together for a simple 5 V
design. In addition to the voltage flexibility, the
dedicated V
PP
pin gives complete data protection
when V
PP
≤
V
PPLK
.
Internal V
PP
detection circuitry automatically
configures the device for optimized block erase and
program operations.
A Command User Interface (CUI) serves as the
interface between the system processor and
internal operation of the device. A valid command
sequence written to the CUI initiates device
automation. An internal Write State Machine (WSM)
automatically executes the algorithms and timings
necessary for block erase, program, and lock-bit
configuration operations.
A block erase operation erases one of the device’s
64-Kbyte blocks typically within one second (12 V
V
PP
), independent of other blocks. Each block can
be independently erased 100,000 times (1.6 million
block erases per device). A block erase suspend
operation allows system software to suspend block
erase to read data from or program data to any
other block.
Data is programmed in byte increments typically
within 6
µs
(12 V V
PP
). A program suspend
operation permits system software to read data or
execute code from any other flash memory array
location.
New Features
The 5 Volt FlashFile memory family maintains
backwards-compatibility with Intel’s 28F008SA. Key
enhancements include:
•
•
•
SmartVoltage Technology
Enhanced Suspend Capabilities
In-System Block Locking
They share a compatible status register, software
commands, and pinouts. These similarities enable
a clean upgrade from the 28F008SA to 5 Volt
FlashFile products. When upgrading, it is important
to note the following differences:
•
Because of new feature and density options,
the devices have different device identifier
codes. This allows for software optimization.
V
PPLK
has been lowered from 6.5 V to 1.5 V to
support low V
PP
voltages during block erase,
program, and lock-bit configuration operations.
Designs that switch V
PP
off during read
operations should transition V
PP
to GND.
To take advantage of SmartVoltage tech-
nology, allow V
PP
connection to 5 V.
